Description

Technical Field

[0001] This utility model relates to the field of rubber production equipment technology, and in particular to a crushing device for rubber production. Background Technology

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can undergo large deformations under small external forces, and can return to its original shape after the external force is removed. Typically, the production of rubber products requires the raw rubber material to be crushed, and then melted and cast to form the final product. However, existing rubber crushing equipment is not precise enough in cutting the raw rubber material, resulting in inconsistent rubber sizes and poor crushing efficiency. Furthermore, the crushed rubber needs to be re-screened during use, reducing the production efficiency of rubber products. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 3 This utility model provides a crushing device for rubber production, including a crushing box 1. The top of the crushing box 1 is provided with a feed inlet 2, and the top of the feed inlet 2 is provided with a guide frame 3. The middle of the crushing box 1 is provided with a crushing component 4, an adjusting component 5, and a screening plate 6 from top to bottom. The bottom of the crushing box 1 is detachably provided with a collection box 7, and the side walls of the crushing box 1 are symmetrically provided with receiving boxes 8. Rubber is introduced into the crushing box 1 from the feed inlet 2, and then slides down along the guide plate 41 in the crushing component 4 to the bottom crushing roller 42. Then, the crushing motor is started. The 45-driven crushing rollers 42 on both sides crush the rubber, and the rubber is blocked by the material blocking part 412 of the guide plate 41 to improve the crushing effect. The crushed rubber is guided to one side of the adjusting component 5 and finally falls to the top of the screening plate 6. It is further screened through the screen holes of the screening plate 6, so that the rubber of appropriate size falls into the collection box 7 for collection, which is convenient for subsequent production. The rubber that is not crushed finely is guided to the material collection boxes 8 on both sides for collection, which is convenient for secondary crushing. This device can easily realize the crushing and screening operation of rubber raw materials and improve its practicality.

[0023] Furthermore, when the collection box 7 and / or the receiving box 8 are about to be full, the control motor 53 drives the sealing plate 52 to rotate synchronously, sealing the openings 9 of the two guide plates 51 on both sides, preventing the crushed rubber from falling to the top of the sieve plate 6, which facilitates further processing of the rubber collected in the collection box 7 and / or the receiving box 8. At the same time, the crushing process is carried out in the crushing box 1, reducing the impact of dust on the environment.

[0024] like Figure 2 and Figure 3As shown, specifically, the guide frame 3 is provided with a chute 31 in the middle, and a baffle 32 is slidably provided in the chute 31. A handle 33 is provided on one side of the baffle 32. By pulling the handle 33, it is easy to control the baffle 32 to move along the chute 31, open the feed port 2 to facilitate the feeding of rubber to be screened, or close it to prevent the rubber from jumping out of the feed port 2 during crushing, and at the same time reduce the impact of dust on the environment during crushing.

[0025] Specifically, the crushing assembly 4 includes a guide plate 41 symmetrically arranged in the middle of the crushing box 1, and crushing rollers 42 symmetrically rotated at the bottom of the guide plates 41 on both sides. The ends of the crushing rollers 42 on both sides are engaged with transmission wheels 43. The side wall of the crushing box 1 is provided with a motor base 44. The motor base 44 is provided with a crushing motor 45 fixedly connected to the end of one side of the crushing roller 42. By starting the crushing motor 45 and engaging with the transmission wheels 43 on both sides, the crushing rollers 42 on both sides are driven to crush and cut the rubber raw material that has been guided to the middle of the crushing rollers 42.

[0026] Specifically, the guide plate 41 includes a guide section 411 and a blocking section 412. The guide section 411 is inclined in the middle of the crushing box 1, and the crushing roller 42 is disposed on one side of the blocking section 412. The guide section 411 of the guide plate 41 facilitates the guide of the rubber to be crushed into the crushing box 1 to the side of the crushing roller 42. The blocking section 412 blocks the rubber during crushing, further improving the crushing effect.

[0027] Specifically, the adjustment component 5 includes a guide plate 51 symmetrically inclined in the middle of the crushing box 1, and a sealing plate 52 rotatably provided at the bottom of the guide plate 51 on both sides. The side wall of the crushing box 1 is provided with an adjustment motor 53 fixedly connected to the end of the sealing plate 52. By starting the adjustment motor 53 to rotate forward and reverse, it is easy to drive the sealing plate 52 to rotate synchronously and seal the bottom openings 9 of the guide plate 51 on both sides, which facilitates further processing of the rubber collected in the collection box 7 and / or the receiving box 8.

[0028] Specifically, the sieve plate 6 is V-shaped, and the sieve plate 6 has several sieve holes in the middle. The V-shaped sieve plate 6 facilitates the guidance of the crushed rubber in the middle of the sieve plate 6 to roll along the two side slopes. During the rolling process, most of the crushed rubber falls through the sieve holes into the collection box 7 for collection and processing. A small portion of the rubber that is not crushed finely will roll into the receiving box 8 for collection. By introducing the rubber collected in the receiving box 8 into the crushing box 1 for secondary crushing and processing, the convenience of crushing of this equipment is improved.

[0029] Specifically, the bottom of the crushing box 1 is provided with an opening 9 for installing the collection box 7. The side wall of the crushing box 1 is provided with guide ports 10 at both ends of the screen plate 6. The bottom of the crushing box 1 is symmetrically provided with overlapping platforms 11.

The rubber rolling along the screen plate 6 rolls further into the collection box 8 through the guide ports 10 for collection. The opening 9 facilitates the disassembly and installation of the collection box 7.

[0030] Specifically, the top side of the receiving box 8 is provided with a guide groove 14, and the bottom of the receiving box 8 is provided with a positioning hole 15 that is inserted and matched with the positioning pin 12. By allowing the rubber to roll from one side of the guide groove 14 to the receiving box 8, and by blocking it from the other side of the receiving box 8 to prevent it from flying out, the recycling effect is further improved.

[0031] Specifically, the positioning pin 12 and positioning hole 15 are connected to facilitate quick and easy material collection and installation onto the top of the corresponding overlapping platform 11.

[0032] The working principle of this utility model is as follows: In use, rubber is introduced into the crushing box 1 from the feed inlet 2. It slides further down the guide plate 41 in the crushing component 4 to the bottom crushing roller 42. The crushing motor 45 is then started to drive the crushing rollers 42 on both sides to crush the rubber. The rubber is crushed by the material blocking part 412 of the guide plate 41. The crushing effect is improved, and the crushed rubber is guided to the adjusting component 5 and finally falls to the top of the sieve plate 6. It is further sieved through the sieve holes of the sieve plate 6. Rubber of appropriate size falls into the collection box 7 for collection, which is convenient for subsequent production. Rubber that is not crushed finely is guided to the two side collection boxes 8 for collection, which is convenient for secondary crushing. This device can easily crush and sieve rubber raw materials, thus improving its practicality.
